The last decade has witnessed a
significant change in the direction of
the CATV industry. The advent of
satellite delivery of premium
programming has broadened the appeal
of CATV as a method to supply home
entertainment. This, in turn, has
resulted in a huge increase in the
CATV subscriber base. However, in
addition to this new base, it has also
resulted in the need for viable denial
technologies to control the
dissemination of this premium
programming.
